After changing my work, I have been busy with the LINUX system architecture, and have gone through the pains of never understanding too much to be familiar with others. In the course of work, Baidu has always been the preferred search engine. But later, I had to and eventually used Google. This helps me better and more. OK.

1.1.1 Surfacecomposerclient
Figure 11?28 Each application corresponds to a client in the Surfaceflinger
Surfaceflinger runs in the systemserver system process, applications that require a UI interface to communicate across processes through the binder service. In the study of audio system, each audiotrack can find a corresponding track implementation in Audioflinger. This design approach also applies to display systems where any program with a UI interface is available in Surfaceflinger and

1.1.1 Surfacetextureclient
The local window for the application side is surfacetextureclient, and like Framebuffernativewindow, it must inherit Anativewindow:
Class Surfacetextureclient
: Publicanativeobjectbase
This local window of course also needs to implement the "Protocol" Anativewindow, and our focus is on how it differs from the previous framebuffernativewindow. The Surfacetextureclient constructor simply invokes the Init function, which as
More and more applications are provided to run on a command-line basis, there are two common approaches: Write a console program that runs on a command line for the application alone, and it must run on a command-line basis when the user runs the program, and share an application or EXE file with the GUI and command line. But through the different arguments to judge, finally does the different processing separately.

Learning from Java Swing:Focus on understanding Container classes (Container) and component Classes (Component):
Java the object created by the subclass or indirect subclass of the component class is called a component
Java the object created by the subclass or indirect subclass of container is called a container
You can add components to a container
The container calls the RemoveAll method to remove all the components in the container
The container itself is also a component
